Abstract
The utility model discloses an embedded type sliding thrust bearing, which comprises a bearing body, wherein friction pieces are arranged on a working surface of the bearing body. Because the friction pieces are arranged on the working surface of the bearing body of the utility model, in the process of use, the surfaces of each of the two opposite friction pieces of each set of the bearings generate relative friction, because the friction pieces are made of superhard materials, the friction coefficient is relatively small when the friction pieces work, the wear resisting performance is very high, so the service life of the bearing can be extended and the bearing is especially suitable for working condition in severe environment.
Description
Technical field
The utility model relates to a kind of sliding thrust bearing, refers to the sliding thrust bearing that a kind of oil drilling mud motor bearing joint upward uses especially.
Background technique
In petroleum industry, because oil drilling need be worked under the environment of drilling mud with mud motor, the solid concentration of mud is very high, and has certain corrosivity, and existing drilling well is a rolling bearing with the thrust-bearing on the mud motor bearing joint, under this very poor operating mode, drilling tool in use often enters bearing because of the grains of sand in the mud, and the rate of wear of bearing is accelerated, and because the jerk during drilling well, the ball of bearing is easy to cracked, and shortened the working life of bearing greatly.
The model utility content
At the problems referred to above, friction factor was little when the purpose of this utility model was to provide a kind of work, wear resistance is high, the inserted sliding thrust bearing of long service life.
For achieving the above object, technical solution of the present utility model is:
A kind of inserted sliding thrust bearing comprises bearing body, and the working surface of bearing body is provided with friction member.
Further, also be provided with one and plate layer on described bearing body, described friction member is fixed in this and plates on the layer.
Further, the described layer that plates plates layer for tungsten carbide tool-scolder, is formed by tungsten carbide tool and scolder sintering.
Further, described scolder can adopt Manic or cobalt base alloy or nickel-base alloy or ferrous alloy.
Further, also be provided with cooling water channel between the described in twos friction member that is provided with on the working surface of described bearing body.
Further, described friction member is embedded in described bearing body or described plating on the layer by the mode of sintering or welding or interference fit.
Further, described friction member is made by cemented carbide or polycrystalline diamond or diamond compact.
After adopting said structure, because the working surface of the utility model bearing body is provided with friction member, in the using process, produce friction relatively on the surface of per two corresponding friction members of every group of bearing, because friction member is made by superhard material, friction factor is less during work, and wear resistance is very high, so can improve bearing working life greatly, this bearing is specially adapted to the abominable working condition of environment.
Description of drawings
Fig. 1 is a sectional drawing of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is user mode figure of the present utility model.
Embodiment:
As shown in Figure 1, the inserted sliding thrust bearing of the utility model comprises bearing body 1 and is arranged at bearing body 1 working surface is friction member 2 on the rubbing surface, this friction member 2 is made by cemented carbide or polycrystalline diamond or diamond compact, the shape of this friction member 2, number and size are not limit, and can determine according to actual needs; For the ease of fixing of friction member 2, on bearing body 1, be provided with one and plate layer 3, this plates layer 3 and plates layer for tungsten carbide tool-scolder, form by tungsten carbide tool and scolder sintering, tungsten carbide tool is the casting tungsten carbide tool, use as framework material, scolder can adopt Manic or cobalt base alloy, nickel-base alloy, ferrous alloy etc. as binding materials; This friction member 2 can be embedded in the body 1 of sliding thrust bearing or plates on the layer 3 by sintering process such as impregnation sintering, hot pressed sintering or welding procedure such as modes such as gas welding welding or interference fit, as shown in Figure 2, for ease of cooling, also be provided with cooling water channel 4 in twos between the friction member at bearing.
As shown in Figure 3, in use, bearing quiet circle A and bearing moving-coil B face-off are placed, under the drive of axle, the bearing moving-coil relatively rotates on the surface of two friction members with bearing Jing Quan and produces relative friction, because friction member 2 is a superhard material, friction factor is less during work, the wear resistance height prolongs sliding thrust bearing working life greatly.
